IMPROVEMEN'l IN TREADLE-POWERS.

Specification forming part of Letters Patent No. 118,273, dated August22, 1871.

To all 'whom t may concern:

Beit known that l', WLLLIAM REED, of Allentown, in the county of Lehighand State of Pennsylvania, have invented a new and useful Improvement inTreadle-Power; and I do hereby declare that the following is a full,clear, and exact description thereof, which will enable others skilledin the art to make and use the same, reference being had to theaccompanying drawing forming part of this speciiication, in Which-Figure l is a side view of my improved power. Fig. 2 is a detailcross-section of the same taken through the line cc cc, Fig. l.

Similar letters of reference indicate corresponding parts.

My invention has for its object to furnish au improved treadle-power fordriving light machinery, which shall be so constructed and arranged thatit cannot set upon the dead-point; and it consists in the constructionand arrangement of various parts of the power, as hereinafter more fullydescribed.

A represents the shaft, from which the power is taken to the machineryto be driven. Upon the shaft A are formed two cranks al a2, projectingfrom the opposite sides of said shaft, and upon the crank-arms of whichare placed frictionrollers B, upon which the treadle-levers C rest.

Upon the under side of the treadle-levers C are formed or to them areattached projections or blocks c', the rear ends of which are beveled orrounded oft' to form inclines, said projections or blocks-being in suchpositions that the roller B of the upper crank, when the said uppercrank is vertical, may be at the beginning of said ineline, so as to becarried by said incline past the dead-point, and into such a position asto be ai'- fected by weight upon the treadle. The treadles C are pivotedat their inner ends to some suitable support, as D, and work betweenguides E, which keep them in position.

The treadles G are operated by an operator standing upon their outerends, near the cranks a1 a2, and throwing his weight upon each footalternately so that the cranks are operated by the weight of theoperator directly.

Having thus described my invention, I claim as new and desire to secureby Letters Patent- The arrangement of the inclines c', treadlelevers C,and cranks al a2 of the driving-shaft A with. each other, substantiallyas herein shown and described, and for the purpose set forth.

VILLIAM REED.
